Light Intensity versus Distance
The relative light intensity versus distance from a point light source is plotted. As the Light Sensor is moved by hand, the string attached to the Light Sensor that passes over the Rotary Motion Sensor pulley to a hanging mass causes the pulley to rotate, measuring the position. The experiment is repeated with an extended source.
Various curves are fitted to the data to see which fits better.PreviewDownload

This system provides a complete set of labs for mechanics, heat, light, sound, and electromagnetism.
The 550 is fast, powerful, and incredibly affordable. It offers half the ports and many of the same features as our 850 Interface in a smaller package.
Designed to perform visible light studies from low intensity spectral studies to daylight. Built in oversampling reduces noise. PASPORT version.
The PASPORT Rotary Motion Sensor measures position, velocity, and angular and linear acceleration.
A complete optics bench that includes all the components required to do introductory optics experiments.
Many lab activities can be conducted with our Wireless, PASPORT, or even ScienceWorkshop sensors and equipment. For assistance with substituting compatible instruments, contact PASCO Technical Support. We're here to help.
